Actually if you open your page with pricing table and open developers tool by pressing F12 button, then click choose elements option and click on the link in the table – you will see the it has nofollow attribute – http://prntscr.com/gjq3s8
But now plugin doesn’t show it has nofollow attribute inside admin area.

We will fix it in one of the next versions of the plugin. I will inform you about the update.
